6 11. In which diagram is the observer experiencing the greatest intensity of insolation? A.. C ase your answer(s) to the following question(s) on the experiment description and diagram below. A student was interested in how the angle of insolation affects absorption of radiation. The student took three black metal plates, each containing a built-in thermometer, and placed them at the same distance from three identical lamps. The plates were tilted so that the light from the lamps created three different angles of incidence with the center of the plates, as shown in the diagram. The starting temperatures of the plates were recorded. The lamps were turned on for 10 minutes. Then the final temperatures were recorded. Explain why the metal plate at a 90 angle of incidence had a final temperature higher than the other two plates. page 6
